why are my prints coming out like this? please help

http://3dprintboard.com/attachment.p...tid=4504&stc=1Hi so i have been using cura with my printrbot jr for about 2 weeks now but i cant seem to get a good print. When i print a 5mm cube it comes out like a blob and when i print a 20mm cube it comes out like this. What am i doing wrong? Thanks in advance.

Looks like one of three issues with your extruder setup:
A) Not hot enough so causing jams(if using PLA try 190c or 230 for ABS)
B) Your tension is off on the extruder causing it to miss steps and not grip filament.
C) Your E steps are not configured correctly.(google for extruder calibration and there are some great guides out there)

I completely do agree with edu3d. I am sure that your E steps have not configured correctly. Please check it once and try again.
